Wtf, Rafa is not stupid enough to play a clay event between the Olympics and the USO come on now
As for Andy, he's not going to the Olympics at all, and he's not even serving or hitting normal forehands right now so there's no way he's gonna come back and win the USO Series that's for sure
Roddick is in deeeeeeeeeeeeep shit. he is dropping in rankings like rock. just hit #9. at this rate, he could get some of tough players early on at the Open. lower rankings would diminish his chances at the Open in my estimation.
he needs a coach fast. Killer Cahill may be of some help in some sort of advisory capacity. i would also consider Tony Roche.
now with respect to open series and Roddick, he could win this upcoming tournament.
